(IMPROVEMENT m GRlNDERS FOR 'HARVESTER-CUTTERS.

The Schedule referred to' in these Letters Patent: and making'part ofthe lathe.

of De Kalb and State of "Illinois, have invented a Grinder for Mower.and Reapcr-Guards; and we do hereby declare that the following is a fulland exact descriptionthereof', which will enable those skilled in theart to make and use the same, reference being had to theaccompanyingdrawing and letters marked thereon making a part of this specification,in which- Figure 1 is a perspective representation of ourimproved'grinder. p T

Figure 2, aplan view of the. stone, rest, 850.

The present'in-ventioh relates to a grindingmacl1ine which is designedto resharpen the fingers of fingerbars of mowers and reapers; and

. Its nature consists in a slotted rest and a traveling pulley-block,for supporting, by means of a chain, the

linger-bar, when the fingers are being ground.

In the present state of the art, when fingers become too dull to operateproperly in grass or grain, they are replaced with new fingers, atconsiderableoostL But hymy invention theycan he. rcsharpened, and thusmade to answer the purpose of new fingers. I

-In fig. 1, N represents floor or foundation, on which is a frame, L L,supporting the journal I of the Attached to that part of the frame shownat L is a projecting block or bed-piece, M, which supports a rest,M'.

This rest is so formed or :forked'as to pass by the periphery of thestone H, and onto its convex sides,

so that a suitable rest for a finger is provided on both sides of thestone.

E E represent substantial 'posts, which have a support on the foundationN, and which support a horizontal beam, E, on the top of which is fixeda metal track, B.

A pulley, A, in pulley-block 0, travels on the track B, and through thelower-part of the block 0 is put a chain, D, which, by means of hooks,suspends the finger-bar F at such height. as will allow the fingers G-to bear onthe'rest M, as shown in fig. 1. By this means the inner sidesof any finger can be readily brought in contact with the stone, while atthe same time the operator is not encumbered with the weight of .thefinger-bar.

When the fingers on one part of the bar have been sharpened, the bar ismoved longitudinally far-enough to bring other fingers-into position.

The stone His rotated by means of a band running over a pulley, K.

Clac' m.

The combination of the forked rest M, frame Ell, track B, pulley andblock A O, and chain D, arranged to operate as and for the purpose setforth.
